Bi-weekly cross-functional sprints

Time frame

Q4 2023

Express Steuer is a tax filing tool. It replaces complex forms with a simple flow, and helps users file taxes quickly, stress-free, and often with a better refund.

Problem

Users dropped off heavily at the final 3 steps of the tax estimation funnel, signalling deep issues of trust and clarity.

Bellow are the result, submission, and legal consent screens

Objective & Approach

Increase conversion from estimation to account creation by improving trust & clarity. We approached it through a broader scope: how can we make experience feel transparent, reliable, and motivating?

Benchmarking

Competitors favor approachable language & live feedback but lack clarity. Wins: trust, progressive disclosure, visible refunds; losses: cognitive load, unclear breakdowns.

Data Analysis

I reviewed existing data, identifying friction, drop-offs, and engagement areas—forming the foundation for the redesign.

A cross-functional session generated ideas tailored for our user segments, product functions & their needs.

Experienced Users

Checks their calculations in full

Frustrated Users

Needs continuous communication

Low Intention Users

Low confidence with Express Steuer

First Time Users

Low on tech. Value human interaction.

Cross-Functional Ideation & Testing

Testing with 15 users revealed confidence in estimates & smoother navigation.

Release

3 releases to balance business prio & tech feasibility. I aligned product and engineering for scope, dependencies, and rollout, ensuring quality while minimising dev risk.

First week A/B testing indicates conversion rate increase by 135% and bounce rate drop by 119%.
